So I’m relatively new to server hosting. (But experienced with remote web hosting from providers.) After about a year of fighting to run Nextcloud on a hosting company and finally losing everything from the cPanel vulnerability a few months ago, I broke down and launched my own home server. I’m looking for advice to maximize security.
CachyOS Linux with ClamAV Docker via Portainer Nextcloud (E2EE), Immich, DocuSeal and NoteTrace Routed through a domain and subdimains via Zero Trust Cloudflare Tunnel and Cloudflare DNS.
I have regular redundant backups both onsite and offsite with Duplicati.
My passwords for OS and all admin dashboards are extremely long, unique, random strings managed by Bitwarden.
I know just enough about this stuff to get into trouble. What else should I setup? I have little to no monitoring going on and don’t know much about that direction.
Can an ISP forbid you having your own home server? That doesn’t sound legal. And if I am not mistaken the cloudflare tunnel is a lot like tailscale (which i would recommend over cloudflare anyway) it doesn’t need open ports or anything like that.
They can forbid you from anything and they can terminate your service for any reason
Which country are you from if I may ask? 😀 I think in EU this would not fly. I think at most they can terminate your service if you torrent a lot but even then I can’t say I saw this happen. Usually they start throttling your internet temporarily and send you email that you should not do it.
